Re: on the ieprep charter

Fred,

So do you think the following statement is roughly true?

"There is enough similarities in the needs of these broad industry 
segements with respect to communications requirements/needs in emergency 
situations that:

a) Protocols can be enhanced (or in some cases developed) to handle the 
similarities, while

b) Differences are relegated to implementations or behavior descriptions."

Thanks,

Bob
